Article Abstract
Background: Durability (ie, the ability to attenuate the decline in performance after accumulated work) has been identified as a performance determinant in elite cyclists. The aim of the present study was to compare durability in elite cyclists of various performance levels, particularly after high-intensity work, referred to as "high-intensity durability."
Methods: Forty-nine (N = 49) male road cyclists were categorized as either under 23 years of age (U23) (N = 11), Pro Team (N = 13), or World Tour (N = 24). The participants' critical power (CP) was assessed during the preseason. Thereafter, the participants' maximum mean power (MMP) values were determined for efforts of different durations (from 5 s to 30 min) after different levels of accumulated work above CP (from 0 to 7.5 kJ·kg-1).
Results: U23 cyclists showed a significant reduction of all relative MMP values for durations ≥1 minute after ≥5 kJ·kg-1 above CP compared with the "fresh" state (0 kJ·kg-1), whereas in Pro Team and World Tour cyclists, a significant reduction was not observed until 7.5 kJ·kg-1 above CP. In the "fresh" state, both Pro Team and particularly World Tour cyclists attained higher MMP values for efforts ≥10 minutes than U23 riders. However, more differences emerged with greater previous work levels, and indeed after 7.5 kJ·kg-1 above CP World Tour cyclists attained higher MMP values than both U23 and Pro Team cyclists for most efforts (≥30 s).
Conclusion: Pro Team and particularly World Tour cyclists tolerate greater levels of accumulated work at high intensity, which might support the importance of high-intensity durability for performance.

Introduction: Power profiling is widely used in cycling performance analysis, but both absolute and mass-normalized power outputs have limitations as performance indicators, as they neglect external factors such as terrain, wind, aerodynamic drag, and pacing strategy. To address these limitations, this study introduced a numerical method to quantify how external forces acting on the cyclist influence the conversion of power output into race velocity. Thus, the study aimed to enable accurate prediction of cycling performance based on estimated mean power output over complex time-trial courses.

Purpose: This exploratory study aimed to determine and compare the external and internal training and racing load characteristics of female professional cyclists during "highly successful" and "less successful" seasons.
Methods: Forty-three seasons of 14 World Tour cyclists (seasons: 3 [1] per cyclist, age: 24 [4] y) over a 7-year period were analyzed (9.036 training and 1.
An investigation into sleep, perceived experiences, and exercise performance in elite male cyclists during the Tour de France.

This study explores the dynamics of sleep, somatic/psychological experience, and exercise performance before, during, and after the Tour de France (TDF). Objective and subjective sleep, self-reported perceived experience, and objective exercise performance data were collected daily from eight elite male cyclists across a 6-week period including the 3-week TDF and 11-day pre- and post-race periods. Associations between, and temporal changes in, primary interest metrics were explored through Pearson correlation and linear mixed models.

Scarce evidence exists on the demands needed to attain the highest positions during Grand Tours (Giro d'Italia, Tour de France, Vuelta a España). Using power output (PO) and heart rate (HR) data, we aimed to compare the racing demands of successful (at least top-5) and less successful (at least top-15) cyclists during Grand Tours. We identified Grand Tours in which we could compare cyclists who had attained a top-5 position (Top) with riders who also competed for the General Classification in the same race but attained a worse position (Non-Top, at least top 15).

This study aimed to examine the key performance metrics and durability differences between cyclists finishing in the top-5 and those ranked between 6th and 30th in the Five Monuments of Cycling (Milan-San Remo, Tour of Flanders, Paris-Roubaix, Liège-Bastogne-Liège, and Il Lombardia). Data from 64 professional male cyclists were analyzed. Cyclists were categorized into top-5 finishers (n = 14) and top-6-30 finishers (n = 50).
